This AAV expresses eArch3.0-EYFP driven by an ubiquitous EF1a promoter.

The 1.2 Kb EF1α promoter is a commonly used, constitutive promoter derived from human elongation factor-1 alpha (EF1α). It is often used in conditions where the other constitutive promoters, such as CMV, have diminished activity or have been silenced.

Arch and ArchT are light-driven proton pumps found in archaebacteria. They provide silencing via hyperpolarization. Only slightly slower than NpHR2, their peak activation falls at 566 nm. ArchT has about a three-fold higher light sensitivity compared to Arch leading to a similar level of inhibition but increased volume of tissue that will be inhibited.

The trafficking signal (KSRITSEGEYIPLDQIDINV) is also from the inward rectifier potassium channel Kir2.1; it serves to dramatically reduce intracellular accumulation and improve membrane targeting, leading to a profound increase of photocurrents. This is the basis for many third-generation optogenetics tools.

This ER export motif (FCYENEV) is from the vertebrate inward rectifier potassium channel Kir2.1. The motif prevents aggregate formation, decreases intracellular accumulations, and enhances tolerability at high expression levels. This is the strategy for developing many second-generation optogenetics tools.

About Storage Conditions

All our viral products should be kept at -80°C. At this temperature, the virus will remain stable for 6-12 months (and in some cases, up to 2 years). Once thawed, the product can be stored at 4°C for 2-3 weeks without significant loss of biological activity. We recommend aliquoting your vectors into low protein binding tubes upon receipt. This helps avoid repeated freeze-thaw cycles, as well as prevent loss of virus. To maintain accurate titer, aliquot in at least 20ul per tube.
